Abstract

Provided is a support leg that prevents a device main body having a vibration source such as a home bread kneader from rotating due to vibration and moving the device main body.
A support leg 15 divides a lower surface in contact with a mounting floor surface into a plurality of regions, and each region is formed with recessed grooves 20a and 20b outwardly, and the recessed grooves in each region are adjacent to each other. The grooves are formed in different directions with respect to the grooves in the matching region. With this structure, since only the convex portions of the concave grooves 20a and 20b are in contact with the mounting floor surface, the support leg 15 is about half the area of the conventional support leg that is in contact with the entire area. The power is reduced and there is little to jump and move. That is, since the supporting leg kicks the floor and jumps to fly, the movement of the device body 1 can be suppressed. Further, when the landing is made by jumping, the groove in the other region is bent and securely gripped, so that further movement can be suppressed.

Description

  The present invention relates to a support leg that prevents a device main body having a vibration source such as a home bread kneader from rotating due to vibration and moving the device main body.

  For example, in a dough kneading machine used at home, kneading blades rotated by an electric motor knead dough material provided in a koji-shaped container to form a dough. Since the kneading machine body vibrates considerably during the process of kneading the bread dough material, support legs for attenuating the vibration and absorbing the vibration are attached to the kneading machine body.

  In Patent Document 1, a bearing-like support leg 10 composed of a large main ball 13 and a small sphere 11 is attached to the lower surface of a device main body 100 provided with a vibration source, and the support is mounted on the floor surface on which the device main body 100 is installed. A vibration absorbing leg 20 that elastically receives the main ball 13 of the leg 10 is provided.

  In Patent Document 2, a holder 40 is attached to the bottom surface of the home appliance 20, and a support leg 50 is attached to the holder so as to be freely screwed. The head 52 that is brought into contact with the floor surface (support surface 30) of the support leg 50 is covered with a soft synthetic resin layer 53, and the length of the support leg 50 is increased by screwing the support leg 50 to and from the holder 40. It adjusts and installs the household appliances 20 on a floor surface (support surface 30).

  For example, in a dough kneading machine, the kneading machine itself is shaken by the vibration when the kneading blades are rotated in one direction by an electric motor to knead the dough material, and the kneading machine moves from the installation location by the shaking, and is near the kneading machine. Drop other members and equipment from the installation floor such as the installation table. The worst kneading machine itself dropped from the table.

  The kneading machine body has flexible rubber support legs attached to the bottom corners to absorb and prevent vibrations. In the structure of the support leg, the lower surface of the support leg (the lower surface to be installed on the floor surface) is configured to be flat so as to be in contact with the floor surface in almost the entire region. However, in reality, the kneading machine moves as described above. Then, as a result of verification by the inventors of how the kneading machine moves, it was found that the kneading machine moves while jumping.

  Since patent document 1 is comprised from the support leg 10 of the bearing structure and the vibration absorption leg 20 which receives this, it becomes a quite complicated structure. Although it is considered that the vibration of the device main body 100 is absorbed by the vibration absorbing leg 20, any of the support legs 10 may be dropped from the vibration absorbing leg 20 depending on an unexpected vibration. In that case, the apparatus main body 100 cannot maintain a horizontal state, and problems, such as having to drive | operate in a dangerous state, arise.

  In Patent Document 2, the length of the support leg 50 can be adjusted to stably install the home appliance 20 on the floor surface (support surface 30). However, since the lower surface of the support leg is a flat surface as in the prior art, the vibration source In the case of home appliances equipped with a skateboard, it is thought that it moves while jumping.

  The present invention solves the above-mentioned problems and prevents the main body of a device having a vibration source from being shaken by the vibration source, moving the device main body from the installation location, and dropping the worst device main body itself. It aims to provide supporting legs.

  The present invention is a flexible synthetic resin support leg that is attached to the lower surface of a device main body having a vibration source and is installed on the mounting floor surface, and the support leg has a lower surface in contact with the mounting floor surface. It is divided into a plurality of regions, and each region is formed with a groove toward the outside, and the groove in each region is formed with a different groove direction with respect to the groove in the adjacent region. And

  Further, the support leg of the present invention is characterized in that the region is divided into two regions, and a concave groove is formed in each region in a direction shifted by approximately 90 degrees.

  On the other hand, according to the present invention, when attaching a plurality of the above-described support legs to the lower surface of the equipment body having a vibration source, the equipment body is attached with the concave groove directed in a direction in which the equipment body vibrates and rotates. It is characterized by becoming.

  The support leg of the present invention divides the lower surface in contact with the mounting floor surface into a plurality of regions, and each region is formed with a groove toward the outside, and the groove in each region is a groove in an adjacent region. In contrast, the support leg of the present invention is formed in a different groove direction, so only the convex part of the groove contacts the mounting floor, so that the contact area is in contact with the entire area compared to the conventional support leg. Since it is about half the area, its kicking power is reduced, and there is almost no jump and movement. That is, since the supporting leg kicks the floor and jumps to fly, the movement of the device body can be suppressed. Further, when the landing is made by jumping, the groove in the other region is bent and securely gripped, so that further movement can be suppressed.

  In addition, since the support leg of the present invention has two regions, and a groove is formed in each region in a direction shifted by approximately 90 degrees, the orientation of the support leg when attaching the support leg to the device body is easy to match. effective.

  Furthermore, the present invention attaches a plurality of support legs to the lower surface of the device main body having a vibration source, because the device main body vibrates and rotates in the direction in which the device main body vibrates. Since the grip force when kicking out becomes weaker and the kicking force becomes weaker, movement of the device body can be prevented.

On the other hand, a support cylinder 19 provided with a projection 17 on the outer periphery is attached to the bottom of the container 2, and a drive gear 18 b fitted to the coupling 18 a is provided inside the support cylinder 19.

  When the support cylinder 19 is placed in the dish-shaped mounting bracket 11 and is rotated a little to engage the protrusion 17 with the locking protrusion 16, the drive gear 18b is engaged with the coupling 18a. The shaft portion 18c of the drive gear 18b is plunged into the container 2, and the kneading blade 4 is detachably attached. The coupling 18a and the drive gear 18b constitute the operating unit 5.

  Next, the detailed structure of the support leg 15 is demonstrated based on FIG. 3 and FIG. The support leg 15 is made of a flexible synthetic resin such as butyl rubber, and the diameter of the lower surface contacting the floor surface on which the kneading machine body 1 is placed is approximately 30 to 50 mm.

  The lower surface is divided into two regions 15a and 15b, and the grooves 15a and 20b are formed in each region 15a and 15b with an approximate 90 degree angle. The width of the groove portions (concave portions) of the concave grooves 20a and 20b is about 1 to 3 mm, the width between the groove portion and the adjacent groove portion (that is, the convex portion) is about 1,5 to 3, 5 mm, and the depth of the concave portion is about 1 to 5 to 3 mm, and the groove in one region is formed in the same direction. A bar-like screw 20 c for attaching the support leg 15 to the bottom surface of the kneading machine main body 1 is integrally provided on the upper part of the support leg 15. In FIGS. 3, 5, and 6, black portions represent the concave portions of the concave grooves 20 a and 20 b, and white portions represent the convex portions.

  The support legs 15 are attached to the four corners of the bottom surface of the kneading machine main body 1 with rod-like screws 20c. When attaching the support leg 15 to the kneading machine main body 1, the direction of the concave groove 20a is attached by aligning the direction of the concave groove with the arrow direction in which the kneading machine main body 1 jumps and rotates as shown in FIG.

  Next, the operation of the bread dough kneader will be described. First, bread dough materials made of flour, water, yeast, and the like are put into the container 2. Next, when the operation switch of the operation panel unit 7 is pressed, an operation signal is sent from the operation panel unit 7 to the control circuit unit 6, and the control circuit unit 6 drives the electric motor 3 based on the operation signal. The rotation of the electric motor 3 is transmitted to the kneading blade 4 through the operating portion 5, and the kneading blade 4 rotates at about 400 to 500 rpm in the counterclockwise direction (left direction) to knead the dough material. As the kneading blade 4 rotates, the dough material rotates in the same direction as the kneading blade 4 rotates.

  The kneading machine body 1 tries to rotate in the clockwise direction (right direction) as shown by the arrow in FIG. 3 by the reaction of the rotation of the bread dough material. In the present invention, the support leg 15 is attached to the four corners as shown in FIG. 3, and the direction of the concave groove is directed toward the direction of rotation (outward), so that the gripping force when kicking out is weakened. Since the raising force is weakened, the kneading machine body can be prevented from jumping up and moving.
